Bøker i Vulgar the Viking-serien

Vulgar has to go back to school, and he is miserable about it. However, his gloom turns to excitement when he discovers that the famous Viking explorer Otto the Bone-Cruncher has joined the school to teach hunting. But when Vulgar is forced to sleep on rocks, wash in freezing streams and eat raw slugs, life as a hunter doesn't seem quite so cool.
